A Garbage Man in Colombia Has Made a Community Library From Discarded Books

Jose Alberto Gutierrez doesn’t just turn trash into treasure—he transforms it into a free education for neighbors. As The Telegraph reports, the middle-aged garbage collector in Colombia has spent the past two decades collecting discarded books he finds while on the job in Bogota, the country’s capital city. Thousands of titles later, Gutierrez has an enormous library, which he and his family lend out to the community for free.

Gutierrez’s library is called La Fuerza de las Palabras, which is Spanish for "The Strength of Words." The collection fills several rooms in his home—and thanks to donations, it continues to grow. (So much, in fact, that the Gutierrez family can no longer squeeze reading groups for children inside their house.) Today, the family is expanding their public literacy mission—and getting rid of extra books—by delivering titles to Colombia’s poor and rural areas.

Gutierrez grew up poor, but his mother instilled in him a love of reading. Now that the home librarian is older, he wants to share this passion with other low-income kids: "The whole value of what we do lies in helping kids start reading," Gutierrez told Al Jazeera.

How to Rig Your Android Phone to Play Old Floppy Disk Games

Owning a smartphone means you have thousands of games at your fingertips, but capturing the nostalgia of playing a game saved on a floppy disk isn't as simple as downloading an app. Reviving floppy disk games for the smartphone era is a bit more complicated, and YouTube vintage video game reviewer LGR shows you just how to do it step by step.

In this video, spotted by Kotaku, LGR takes an old floppy disk, the same kind you used in your computer class at school, and uses it to play a classic video game on a smartphone. This is made possible with an Android phone, a USB connector, an Android USB adaptor, and a portable floppy disk drive that's about as big as the phone itself. (The hardware doesn't work for iPhones, but if you're an Apple user there are plenty of ways to play old PC games online).

Just inserting the disk into the drive when it's connected to your phone isn't enough to start playing: You need to download a special app that mimics Microsoft's old disk operating system, like Magic Dosbox, for example. Once you have that on your phone, you can use it to open whatever game is saved to your floppy disk.

Because old PC games weren't made for touchscreens, the smartphone gameplay can be a little be a little awkward—but if you're willing to hook a floppy disk drive up to your phone, convenience likely isn't your goal. You can watch LGR's full instructions in the video below.

Can You Solve the Arithmetic Problem That's Stumping the Internet?

How much do you remember about arithmetic? This math problem spotted by Pop Sugar will put your knowledge of high school-level math to the test.

According to YouTube channel MindYourDecisions, the problem (9 - 3 ÷ 1/3 + 1) went viral in Japan after a claim was made that only 60 percent of 20-year-olds could get the correct answer.

Inputting this problem into a calculator won’t work—it will interpret the division incorrectly—so you’ll have to solve it the old-fashioned way to get the right answer. The answer may seem obvious to those who remember to “Please Excuse My Dear Aunt Sally” (a mnemonic device for PEMDAS, the order of operations).

Since there are no parentheses, exponents, or multiplication signs in this equation, the first part you’d tackle is division (3 ÷ 1/3). You should end up with 9, which will bring you to 9-9+1. Next up in the order of operations are addition and subtraction, which are performed from left to right. That should bring you to 0+1, and finally, a grand total of 1.

Did you get it? Common mistakes may lead you to 3, 7, 9, or -1, but try it again with Aunt Sally in mind and you should get the right answer.
